What do the colors on the contour map of Putuoshan (291m) mean?

The contour map uses a hypsometric color scale where green represents lower elevations, yellow and orange indicate mid-range altitudes, and white marks the highest zones near the summit. Thicker contour lines (index contours) are drawn at wider intervals to help you quickly estimate elevation.

What is the contour interval for Putuoshan (291m)?

The contour map of Putuoshan (291m) uses a 10m contour interval. This means each line represents a 10m change in elevation. Closely spaced contours indicate steeper terrain, while widely spaced contours show gentler slopes.

What does the elevation profile of Putuoshan (291m) show?

The elevation profile is a cross-section through Putuoshan (291m) from west to east, passing through the summit at 291m. It reveals the mountain's shape, steepness, and relative height compared to the surrounding terrain. The horizontal axis shows distance in kilometers from the peak.

Why does Putuoshan (291m) have elongated ridges?

Putuoshan (291m) was formed by tectonic folding, which compressed rock layers into long, parallel ridges. The contour map shows elongated lines that follow the axis of the fold, rather than circular patterns.
